I’m building a Garbage Detection Workflow (Image recognition) with KNIME and Keras. As an Example/Tutorial is used this Workflow provided by @stelfrich and also a second Workflow provided by @ScottF .
When I execute the Keras Network Lerner Node I receive the following error:
WARN Keras Network Learner 0:10 C:\Users\svn.conda\envs\py3_knime_dl\lib\site-packages\keras\engine\saving.py:292:
UserWarning: No training configuration found in save file: the model was not compiled. Compile it manually.
ERROR Keras Network Learner 0:10 Execute failed: Node validation data size for input/target ‘input_1_0:0’ exceeds the expected size. Neuron count of this input/target is 784, batch size is 32. Thus, expected validation data size is 25088. Please check the column selection for this input/target and validate the node’s validation data.
This is just an example, I tried several configurations with the Keras Nodes (less or more Neurons, less or more batch size etc.).
Where can I/need to have to change the configuration?
